This breaker includes a communication function and comes with one auxiliary switch plus one trip alarm switch. The ETU560 trip unit gives you adjustable protection curves and a local trip indicator so when it does open, you know why. ## Thermal derating — what 400 A really means at your ambient At 55 °C it's still good for 375 A, at 60 °C for 350 A, and so on down to 300 A at 70 °C. If your switchroom runs hot, this gives you a clean derating curve to work with instead of guessing.","metaTitle":"Siemens 3VA2340-6JQ32-0AG0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens 3VA2340-6JQ32-0AG0 SENTRON molded case circuit breaker. 400 A continuous, ETU560 trip unit, 242 kA at 240 V.
